ITEM 4.  CHANGES IN REGISTRANT'S CERTIFYING ACCOUNTANT

     (a)  On July 25, 1996, Oregon Steel Mills, Inc. (the "Company")   
     dismissed its prior certifying accountants, Coopers & Lybrand     
     L.L.P. ("C&L").  

     (b)  The reports of C&L on the financial statements of the        
     Company for the two fiscal years preceding the date hereof        
     contained no adverse opinion or disclaimers of opinion and were   
     not qualified or modified as to uncertainty, audit scope or       
     accounting principle.

     (c)  The decision to dismiss C&L was approved by the Company's    
     audit committee of the board of directors and ratified by its     
     entire board of directors.

     (d)  During the two most recent fiscal years and the subsequent   
     interim periods to the date hereof, there have been no            
     disagreements with C&L on any matter of accounting principles or  
     practices, financial statement disclosure, or auditing scope or   
     procedure, which disagreements if not resolved to the             
     satisfaction of C&L would have caused them to make reference      
     thereto in their report on the financial statements for such      
     years.

     (e)  During the two most recent fiscal years and the subsequent   
     interim periods to the date hereof, there were no reportable      
     events (as such term is defined in Item 304(a)(1)(v) of           
     Regulation S-K).  
          
     (f)  The Company has requested that C&L furnish it with a letter  
     addressed to the Securities and Exchange Commission stating       
     whether or not it agrees with the above statements.  A copy of    
     such letter will be filed as an Exhibit to an amendment to this   
     Form 8-K within 10 business days of the filing of this report.
